An intelligent receiving system for disaster early warning information based on (Digital Multimedia Broadcasting) DMB is proposed. Through the study of DMB transmission protocol standard, real-time receiving scheme of multimedia information for disaster warning information is put forward, including text information, audio information and video information. Aimed at the research for the algorithm of region-selectivity of receiving and the design for feedback control unit, the function of intelligent receiving is realized. By the research of the system, single receiver mode (Digital Audio Broadcasting, DAB) for text and audio information at present has been changed and multimedia receiver method of disaster early warning is achieved for the first time. Meanwhile, theory difficulty of region-selective receiving is implemented. The receiving capability of disaster early warning is improved in real-time, accuracy and diversity.
